(1)Dynamic focus

Checking the Dyn.Focus check box enables dynamic focusing (the function that varies the focusing in tandem with the scanning process). The adjustment slider and the micro- adjustment button can be used to make adjustments so that the image will be in focus over the entire screen.

The possible range of adjustment is ±100(±70°) so that compensation can be made in both positive and negative directions of tilt. These numbers are index values, not angles. Adjustments should be made by viewing the focus on the image.
